Many shorting plugs include springs that disconnect the signal after removing the plug from the guitar. These springs can wear over time resulting in malfunction and possible damage to your equipment. Planet Waves Circuit Breaker Instrument Cable will save your equipment from loud pops and squeals while changing guitars with a live amp. When the button is pushed, the cable shorts while remaining plugged in your guitar, making on-stage guitar changes a snap, and eliminating any chance of sound bursts. Plus, since the cable can be shorted without removing the plug from your instrument you can also use the cable to prevent unwanted noise or feedback during breaks from playing. Once the cable is shorted, remove the cable from the guitar being used and plug the cable into the next instrument. Press the button again to re-activate the cable signal. It’s that easy!!! Each plug is plated with 24-karat gold and has 8 compression springs that allow the plug to positively lock into the jack, eliminating any annoying static. The Planet Waves Circuit Breaker cable is simply the safest way to prevent damage to your equipment live or in the studio.
